After tons of speculation, confirmation has come that Mary-Kate and Ashley Olsen will officially not be a part of the upcoming Netflix reboot and reunion series, Fuller House.  

The show, which picks up decades after the original 90s series left off and predominantly follows the story of a recently widowed DJ (Candace Cameron Bure), who asks her best friend Kimmy (Andrea Barber) and sister Stephanie (Jodie Sweetin) to move in with her shortly after, is set to have an initial reunion episode with nearly the rest of the original cast--but now, the Olsen twins, who shared the role of youngest Tanner sibling Michelle, have officially opted out of the show.

"Although Ashley and Mary-Kate will not be a part of Fuller House, I know how much Full House has meant to them and they are still very much considered family," executive producer Robert L Boyett said in a statement. "It has been exciting to see how they have built their professional careers, and I suport their choice to focus on their fashion brands and various business endeavors. I appreciate their support and good wishes towards Fuller House."

And while fans are sure to be sad that the twins aren't returning, their fellow cast members have also expressed sadness at their decision not to come back for the new show on social media, with John Stamos admitting he was heartbroken, but still wished the two the best.

" #heartbroken," he tweeted around 9 p.m., before adding, "I understand they're in a different place and I wish them the best. I promise you will not be disappointed with our reunion and spin off!!"

The news also came on a big day in Full House history, with the 20th anniversary of the show's final episode also being on the same day that the news about the Olsens was confirmed--a fact that Barber remembered and shared on her own Twitter page.

"5/23/95--20 yrs ago today, Full House aired its final episode. Can't wait to continue this journey. #FullerHouse," she wrote.
